This o-ring is supplied in AS568-325 red Silicone 70 Shore A with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm), catalogued under part number S70MD325. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is specified for an exceptionally wide service temperature range, physiological inertness and low toxicity. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or concentrated acids call for a different compound.
This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across medical devices, food and beverage processing, and sanitary process lines.
S70MD325 ships individually. Nominal inside diameter is listed as 1 1/2 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
